Just when you thought that your favorite celebs couldn’t be any more impressive, they do something like head on to a late night talk show and reveal that, in addition to singing or acting, they’re also a master sword swallower and can yodel the alphabet backwards in perfect French… or something similar.

Read on for some of the craziest and most surprising celebrity hidden talents.

Kendall Jenner

Supermodel, reality TV star, and Kardashian sister Kendall Jenner is probably best known for her photogenic appearance and recent catwalk domination. But were you aware that she’s also really, really good at making bird sounds? She first revealed her hidden talent during an August 2016 Vogue “73 Questions” video questionnaire, and then again in February 2017 on The Late Late Show With James Corden.

Chloe Grace Moretz

Looking at petite Kick-ass actress Chloe Grace Moretz, you wouldn’t exactly expect her to be, well, kick-ass at handling knifes.But… surprise! She’s not just good at it, she’s great, as she showed off on Late Night with Conan O’Brien. In fact, she told O’Brien that she’d been practicing the skill since she was 11 years-old, and held the conversation while she flipped her butterfly knife all the while. Wow.
